Controller and User Interface Device, Systems, and Methods

ABSTRACT

A data collection system controller that includes a housing such as a cover. The housing includes a user facing section and a support facing section defining a hole. The controller also includes a first input device adjacent the user facing section and a second input device. The second input device includes a knob comprising a third input device and a rotatable shaft extending through the hole and partially disposed within the knob. In one embodiment, the second input device is an XYZ joystick with a button. In one embodiment, the joystick and the first input device are angled relative to each other on either side of an elbow joint. In part, the invention relates to a method of controlling the display of image data obtained with respect to a blood vessel.

BACKGROUND

Ultrasound-based imaging systems, such as intravascular ultrasound (IVUS) imaging systems use various control devices. For example, some IVUS systems use a pointing device as a control device. Such pointing devices can include trackballs, touch pads, touch sensitive monitors, mice, and two dimensional or XY joysticks. Since these devices are used in the context of a catheter-based procedure, they generally must be used in a sterile environment such as beneath a sterile drape. These devices have various limitations, some of which are outlined below.

Examples of some of the device specific limitations are outlined herein. Touch-sensitive monitors both display information and receive control inputs. As a result, they fail to serve as a discrete control device. With a touch monitor, a user must reach across the work surface to control the system. Trackball controllers, touch pads, touch monitors, and mice are difficult to use under a sterile drape. In addition a trackball lacks certain mouse functions. Touch-based devices such as touch pads are prone to accidental actuation. Mice are prone to fall off of a work surface. A two dimensional or XY joystick is challenging to use for “click and drag” functions for which a mouse is preferred. These limitations and others interfere with and add complexity when controlling a data collection system during or after a procedure such as an OCT, FFR, or IVUS procedure.

In addition, these various devices are often presented to a user in an orientation prone to cause carpal tunnel or other types of discomfort from use during or after a procedure. Accordingly, a need therefore exists for controllers that address these deficiencies. The present invention addresses these needs and others.

DETAILED DESCRIPTION

In part, one embodiment of the invention relates to a controller and user interface software suitable for use with a data collection system such as an intravascular ultrasound system, an optical coherence tomography (OCT), a fractional flow reserve (FFR) system, angiography systems, combination systems such as a dual OCT and IVUS system or other suitable systems. These controllers and user interface software can be used in, near, or remote from a catheter lab, but are configured to integrate with or control the display of data obtained during a data collection procedure such as catheter-based procedure. One such procedure is an optical coherence tomography pullback. An exemplary catheter lab 5 is shown in FIG. 1A. Data is collected in such a lab 5 in some embodiments using a probe inserted in a patient disposed on a table or other support 20.

As shown in FIG. 1A, a controller 10 suitable for controlling a data collection system such as an OCT, FFR, IVUS, angiography, or other system is depicted. A user can interact with the data collection system or otherwise access and display stored image data through the mountable controller 10. The controller can be mounted to a support member 15 such as an accessory rail on a table, bed or other support 20. The support member 15 can be part of the support 20 or the controller can attach directly to the support 20 in one embodiment. In one embodiment, the controller 10 includes an attachment device 60 such as a clamp for mounting as shown. The controller 10 can be used to display and navigate a graphical user interface displayed on one or more monitors 23. In one embodiment, the monitors can be mounted on a ceiling suspension. A graphical user interface 27 can be displayed on a given monitor.

In one embodiment, the controller has a feature set configured to map to commands and menus available to a user as part of the graphic user interface 27. An angiography system 25 can be positioned relative to the support 20 to obtain x-rays of the patient while another data collection procedure such as an OCT procedure is underway. The graphic user interface 27 can display such OCT, angiography, FFR, IVUS, and other data of interest to a user. The controller 10 is configured to control the interface 27 and navigate the menus and image display features it presents to a user.

In part, one embodiment of the invention relates to a controller configured for use with a graphical user interface configured to represent and navigate data obtained during an OCT, FFR, IVUS, angiography, or other cardiovascular or lumen related data collection procedure. The controller and software are configured to operate in tandem in one embodiment to provide rapid access to commonly used functions associated with a given optical coherence tomography image dataset with a minimal amount of actuation. The surfaces of the controller and input components are prepared for use beneath a sterile drape while wearing medical gloves in one embodiment. The surfaces can include ridges or other surface features that facilitate gripping and actuation of input devices beneath a sterile drape. The controller and software are designed to operate with generalized software drivers such that they can be used with a plurality of configurations of a given image data collection system. The controller can also be used as a mobile data collection system console such that remote control of such as system is handled via the controller.

The controller and GUI combination allows the user to rapidly review and manipulate data such as OCT and FFR data without the need for actions, such as mouse clicking and dragging. These actions and others that are awkward to perform beneath a sterile drape are avoided or easier to perform using the controller. This is achieved primarily by using a joystick that can be twisted clockwise and counterclockwise in addition to being moved in a conventional XY motion. The controller includes a wireless communication device. Thus, in one embodiment, the controller can link wirelessly to a mobile data collection system to provide the user with control near or remove from a patient or procedure room.

An exemplary embodiment of a controller suitable for controlling one or more functions of a data collection system such as its display or image data navigation function is shown in FIG. 1B. The controller includes a housing, such as an outer shell, which can be a continuous housing or be formed from a plurality of housing components. For example, the housing can include an upper housing 12 and a lower housing 14. The controller 10 is shaped to present one or more input devices to a user such that ease of use and comfort are facilitated by the angled orientation of one or more input devices. The controller 10 can have a hockey stick, elbow or L shaped configuration when viewed from a side. Notwithstanding the forgoing, the controller can have various surface geometries and angled sections configured to present various input devices such a as joystick and inputs such as buttons or switches at an ergonomic angle. The forward bias of the joystick enhances actuation and improves ergonomics during a procedure.

As shown in FIG. 1B, the input devices are disposed along different sections of the controller. Exemplary control devices including buttons or switches A1 to A6 are shown arranged in one section of the controller. Another input device can include an actuatable elongate member 50 such as XYZ joystick with a rotatable knob. The elongate member 50 can include a cover or grip 53. A button 55 can be disposed on or in a surface of the cover 53. This member 50 can be twisted and the button can be configured to operate a mouse button when interacting with interface 27.

In turn, the housing such as upper housing 12 can define one or more holes or cavities. These holes can be sized and arranged to allow switches and a joystick such as elongate member 50 to be accessible by a user. The controller includes an attachment device 60 suitable for attaching the controller or a controller dock to a support such as a table, bed, gurney or other suitable support. In one embodiment, the elongate member 50 is a joystick that includes a forward tilt bias. The forward tilt bias of the joystick substantially improves ergonomics over existing devices such as trackballs and XY joysticks.

In one embodiment, forward tilt bias refers to the feature that a component of the controller such as a joystick or other pointing device is disposed on a plane or structure tilted as angle relative to the floor, the surface of a support structure disposed on the floor, or a plane parallel to either of the foregoing. For example, in one embodiment, a pointing device with an elongate member such as the post of a joystick that has a forward tilt bias is positioned such that a user of the device's hand bends toward the floor with a reduction in strain in contrast with the hand bending upwards with an associated increased level of discomfort and strain at the wrist associated with a backward bias. This is advantageous to the operator of the controller because the operator's hand rests at a natural position when manipulating the controller, improving the ergonomics of operation. The panel containing the buttons A1 to A6 may have a reverse tilt bias in order to prominently display the buttons A1 to A6 to the user such that they are not obscured.

The controller can have various shapes and oriented sections configured to present the user input devices such as buttons or a joystick to a user. As shown, the controller can include a user facing section 30 and a support facing section 40. In one embodiment, these sections do not have an absolute starting or an ending point, but come together at a bend or joint that resembles an elbow shape. The angle Z at which these two sections are positioned relative to each other can be obtuse or acute depending on the embodiment. Z ranges from about 45 to about 180 degrees in one embodiment. The user facing section is tilted at an angle to a user to facilitate hand actuation. This angle is maintained when the controller is attached to a support such as via a support member 15.

In one embodiment, the support facing section 40 is tilted at an angle to the support, but is positioned to allow access to an input device. In one embodiment, an attachment device 60 is at one end of the controller, a first input device is at the other end of the controller, and in between the first input device and the other end of the controller a second input device is positioned. In one embodiment, the second input device is positioned in the vicinity of the bend between the two sections of the controller. The attachment device 60 can attach to the support 20 or support member 15 shown in FIG. 1C in one embodiment.

FIG. 2A shows a controller 10 with various reference segments J and K and L and zones Z1, Z2, and Z3. The angle between segment J and K is A degrees. The angle between segment K and L is B degrees. A can range from about 110 to about 180 degrees. B can range from about 45 to about 180 degrees. Segments K and L can be drawn along a midline or another line that spans sections 30 or 40 in one embodiment. Segment J can be positioned in a plane parallel to the support 20 in one embodiment.

The elongate member 50 can include a knob having an outer cover or grip 53. The outer cover 53 can be a pliant deformable material such as rubber or plastic and can include grip structures 56 such as ridges, bumps or indentations. The elongate member 50 is disposed in zone Z3 in one embodiment. Another input device such as one or more buttons is disposed in zone Z2 in one embodiment. Zone Z1 represents a sterile zone such as can be achieved using a sterile drape. FIG. 2C shows another controller 10 embodiment. Zones Z1 and Z2 can be arranged to form ergonomic input zones that are presented to a user based on the angle at the attachment region of the attachment device 60 and the support 20 and the shape of the controller 10.

FIGS. 3A-3E show various perspective views of another controller embodiment. As shown in the figures, various subsystems, components, holes, cavities, and fasteners are shown. These are provided as example embodiments. As shown in FIG. 3A, the upper housing 12 and the lower housing 14 can be separated and attached using various fasteners F. When attached, the housings 12, 14 are connected to attachment device 60, which is a clamp in one embodiment. The attachment device 60 includes an attachment zone 62 for connecting to a support 20 or support member 15. An attachment plate 70 and a faster 70 a can be used to engage and secure the attachment device 60 to the controller. An interface plate 73 can also be disposed in the recessed region 35 of housing 12.

A backplate 74 can be attached on the other side of housing 12 to secure the interface plate 73. This interface plate 73 can define holes for buttons as shown in FIG. 1B. A joystick module 77 can also be sandwiched between the upper housing 12 and lower housing 14. An electronics and connector module 79 which can contain a programmable processor or other circuitry can also be disposed in between the two housings 12, 14. \As shown in FIG. 3B, a hole 75 is defined by the upper housing 12 to receive the elongate member 50 which is formed from the joystick module 77 and cover 53 in one embodiment. Various fasteners F can be used to secure the upper and lower housings.

FIG. 3C shows a controller embodiment with various arrows indicating the rotatable nature of the elongate member. The top button 55 is also shown for the knob or top portion of the elongate member. The attachment device 60 is shown in a secured or closed configuration. A ridged region 83 of clamp 60 configured for pressing upon by a user is also shown.
